Brief Description

Sdbot.LJJ is a backdoor that allows hackers to gain remote access to the affected computer in order to carry out actions that compromise user confidentiality and impede the tasks performed on the computer.

It captures certain information entered or saved by the user, with the corresponding threat to privacy:
passwords saved by certain Windows services.

It sends the gathered information to a remote user by any available means: email, FTP, etc.

It reduces the security level of the computer:
it listens on open ports in order to control the computer remotely; it awaits remote-control orders received through
IRC.

It uses stealth techniques to avoid being detected by the user:

It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.

Sdbot.LJJ uses the following propagation or distribution methods:

Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.

Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
